SAFE CORNER CONSTRUCTION.

Application filed January '7, 1924. Serial No. 684,729.

To all whom it may concern:

Be it known that I, CHARLES J. Barns, J12, a citizen of the UnitedStates, residing at Englewood, county of Bergen, and State of NewJersey, have invented certain new and useful Improvements in Safe CornerConstructions, of which the following is a specification.

This invention relates to safe construction, and more particularlyrelates to the corner construction of safes incorporating angle ironsbounding the edges of the safe.

Heretofore it has been customary to miter the bounding angle irons ofsafes, safe cabinets or the like at the corners of the safe and to weldthe meeting edges together from the outside, and then to trim off theseam on the outside by a grinding process. To reduce the number of suchseams in a safe the bounding angle irons sometimes have been bent aroundone or more of the corners. The mitering and bending must be accuratelydone, requiring great care and considerable time.

The principal object of my invention is to provide an improved method ofconstructing the corners of safes, safe cabinets, or the like, havingmetallic edge members, whereby with less time and care a strongerconstruction may be had. Another object of my invention is to provide amethod of constructing the corners of a safe, safe cabinet or the likehaving metallic edge members, without requiring the edge members to beaccurately mitered or cut, permitting the use of separate lengths ofangles, and permitting the corner joint to be established by weldingfrom the inside, and thereby securing a neat joint or seam withoutrequiring trimming off or grinding. A further object of my invention isto provide a safe corner construction which is extremely strong, and atthe same time is simple and may be easily and inexpensively produced.Other objects of my invention will be in part obvious and in partpointed out hereinafter.

In accordance with this invention, a separate piece is provided, shapedto it over a corner of a safe, safe cabinet or the like. Such cornerpiece may be designed to overlap the ends of the edge frame memberswhich approach the corner, permitting the ends of the framing members tobe welded square as desired.

to the corner piece by spot welding or by welding only from the insideof the construction, and in either case the ends of the frame membersmay be mitered or cut off In this way the corner incorporates theadditional reenforcement of the overlaid corner piece and at the sametime may be easily and quickly built up, avoiding the necessity ofaccurately cutting and fitting together the ends of the frame members,and, when the welding is accomplished along the seams entirely on the inside of the construction, the necessity of trimming or grinding on theoutside to obtain neatness and a finished appearance is eliminated. Ifdesired, however, the corner piece may be so designed that the angleirons, cut off square, will abut the edges of the corner piece and maybe secured thereto by butt. welding, instead of accomplishing the weldby hand. By using the separate corner piece a neat uniformity ofrounding is obtained which is practically impossible when the angle ironis rolled around a corner. I s

In order that a clearer understanding of my invention may be had,attention is hereby directed to the accompanying drawings forming a partof this application and illustrating certain possible embodiments of myinvention. Referring to the drawings, Fig. l is a perspective View of acorner fragment of a safe looking from the outside of the construction;Fig. 2 is a perspective view of the same looking from the inside of theconstruction; Fig. 3 is a sectional view of one of the seams or joints,and is taken on the line 38 of Fig. 2; Fig. 4 is a perspective view of acorner fragment of a safe having a slightly modified embodiment of myinvention, the View showing the exterior of the construction; Fig. 5 isa perspective view of the same looking from the interior of theconstruction; Fig. 6 is similar to Fig. 5 but shows spot welding betweenthe angle irons and corner piece; Fig. 7 is an exterior perspective viewof a corner fragment of a safe showing a modified form of construc tion;and Fig. 8 is a sectional View thereof and is taken on the line 88 ofFig. 7 Similar reference characters refer to similar parts throughoutthe several views of the drawings.

Referring to the drawings, the corner construction illustrated in Figs.1, 2 and 3 comprises usual body walls 1 and edge frame members .2 Whichare angular in cross section and are secured along their side edges tothe edges of the body Walls 1. Instead of bending one of the members 2about the corner or welding the ends ofthese members together at thecorner from the outside, I provide a separate corner piece 3, shaped tofit over the corner and to overlie the ends of the frame members 2. Ithen weld the ends of the framing members 2 to the inner surface of thecorner piece 3from the inside of the construction, as at at, thus notonly effecting a secure joining of the frame members 2 at the cornerwith the additional reenforcement of the separate corner piece at thecorner, but also securing a neat and even rounding atthe corner. Itbeing possible to perform all the welding on the inside of thestructure, as at 4, it is not necessary to have any welding on theoutside, and, therefore, a neat corner may be constructed withoutentailing trimming or grinding on the outside.

The shape of the frame members 2, ob viously, may be varied considerablyand still be susceptible to joining by means of a suitable corner piece.Moreover, the ends of the frame members 2 may be mite-red or not, asdesired. In Fig. 2 the frame members 2 are shown mitered for adistance,as at 5, and then are cut off square, as at 5.

The frame members 2 illustrated have along their edges outwardlydirected channels 6 in which the edges of the wall plates 1 are seated.The inner walls 7 of the channels are extended and abut the. innersurface of walls 1, to which they are welded, as at 8.

This type of frame member is found to be extremely desirable and isdisclosed inan application filed by Carl Bartels and David H. Bellamoreon July 7, 1921, Serial No. 482,893, Patent No. 1,485,360, issued March4, 1924.

In the modifications shown in Figs. 5 and 6, only the inner flangeportion 7 of the frame members 2 are shown mitered, as at 9, theremainder of the frame members being cut off square, as at 10. In theseembodiments the separate corner pie e 3 is extended somewhat along theframe members 2 so as to sufficiently overlap the ends 10 of the framemembers to permit adequate welding of. the ends of the frame members 2to the corner piece 3, either by welding from the inside, as at 4, inFig. 5, orby spot Welding, as at 4L, as in Fig. 6.

Obviously, if desired, the frame members 2 may be mitered all the way tothe corner. When the frame members are mitered, however, they arepreferably so formed that they will not form a tight fit and will allowsuflicient space for proper welding to the corner piece.

In forming a corner construction in accordance with the above, the framemembers may be cut to length, fitted in, the corner piece applied, andthe parts welded up in very much less time and with considerable lesslabor than would be required to accurately miter the f 'ame members,weld them together from'the outside, and then trim off by a grindingprocess on. the outside. vThis is especially true with. frame memberssuch as are illustrated in the drawings, since it is ditlicult to miterand weld together such frame members accurately due to the channelformation along their edges.

Another possible modification is illustrated in Figs. 7 and 8. In thisembodiment the ends of the angle iron frame members 11 are cut offsquare and directly abut the edges of a corner piece 12 so that they maybe secured to tho cornerpiece by butt welding, as at 13. s

As many changes could be made in the above constructions and as manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

IVhat I claim is 1. In safe construction, in combination, frame membershaving outwardly presented grooves along theiredges, body plates seatedin said grooves, and a separate corner piece welded to; the ends of saidframe members at a corner of the safe.

2. A plurality of frame members having ends meeting at a corner of thesafe and having outwardly presented grooves along thelr edges, bodyplates seated in said lapping the body portions of said frame membersand welded thereto, portions of the said ends of the frame. membersmeeting each other in a mitre joint.

3. A plurality of frame members having ends meeting at a corner of thesafe and having outwardly presented grooves along their edges, bodyplates seated in said grooves, and a separate corner plate overlappingthe body portions of said frame members and welded thereto, portions ofthe said ends of the frame members meeting each other in a-mitre jointand other portions of said frame member ends being cut off square.
